A certain species of grasshopper can have red stripes, yellow stripes, or red and yellow stripes. An RR grasshopper has red stripes, an YY grasshopper has yellow stripes, and an RY grasshopper has red and yellow stripes. A grasshopper with red stripes mates with a grasshopper with yellow stripes. What ratio would you expect to see in the phenotypes of their offspring?
All of the offspring will have RY (Red and yellow stripes). If you set up a punnet square and solve, you will see that all four offspring have RY genotype, therefore their phenotype is red and yellow stripes
